Climbing Rose Stopped Blooming After Bayer 3-in-1 Application

Jackson & Perkins climber bloomed well until Bayer Rose Care (fertilizer + disease control) applied. Then blooming stopped, one long shoot appeared. Leaves healthy. Gardener asks if Bayer caused it.

3-in-1 Products Can Stress Roses

Reports suggest these systemic combos can be harsh, especially if applied in heat (>80°F). The fertilizer component forces vegetative growth (the long shoot) at expense of flowers.

Recovery Plan

• No more fertilizer this season.
• Water only.
• Wait. It will return to normal bloom cycle.

Lesson: Separate fertilizing and spraying. Never apply chemicals in heat.
